opencv讀取攝像頭實時流代碼

opencv讀取攝像頭實時流代碼：

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    VideoCapture inputCamera;
    string videoStreamAddress = "此處填寫攝像機的URL";
    inputCamera.open(videoStreamAddress);

    if (!inputCamera.isOpened())
    {
        cout << "攝像頭打開失敗！" << endl;
        return false;
    }

    // obtain the video parameters
    int rate = inputCamera.get(CV_CAP_PROP_FPS);         //the rate of video frame
    int frameHeight = inputCamera.get(CV_CAP_PROP_FRAME_HEIGHT);  // the height of video frame
    int frameWidth = inputCamera.get(CV_CAP_PROP_FRAME_WIDTH);    // the width of video frame

    Mat cutImage;
    char c;
    while (true)
    {
        inputCamera >> cutImage;

        imshow("cutImage", cutImage);

        c = waitKey(33);
        if (c == 27) break;
    }

    return 0;
